The North Atlantic Right Whale (Eubalaena glacialis) is a baleen whale, one of three Right Whale species belonging to the genus Eubalaena, all of which were formerly classified as a single species. Its coloration is dark grey to black, with some individuals occasionally having white patches on their stomachs or throats. Other unique features include a large head, which makes up a quarter of its total body length, narrow tail stock in comparison to its wide fluke and v-shaped blowhole which produces a heart shaped blow. Because of their docile nature, their slow surface-skimming feeding behaviors, their tendencies to stay close to the coast, and their high blubber content (which makes them float when they are killed, and which produced high yields of whale oil), Right Whales were once a preferred target for whalers. At present, they are among the most endangered whales in the world.
